Having recently upgraded to Mandriva 2010.0, I also wanted to give Cedega a go, so I loaded up the latest Cedega and found that certain CDs and DVDs were not recognised. They would load OK but would not run, failing the “copy-protection” test in Cedega Diagnostics. The game in this case was Oblivion which installed fine but would not run.
I found that I had to manually add an entry to the end of /etc/fstab file, to specifically set the CD/DVD options:
# Entry added to allow Cedega copy-protection test to work. /dev/sr0 /mnt/cdrom iso9660 user,unhide,noauto,ro 0 0
You will need to replace “/dev/sr0″ with the actual location of your CD/DVD drive. You can check where the /dev/cdrom and /dev/dvd links point to get this information. I’d imagine that in most cases “sr0″ will be correct.
Strangely enough the same set up on a notebook worked perfectly without any changes to the fstab file. So it’s obviously only certain hardware configurations that need this change.
